Fisheries sanctuary is the feasible solution that was agreed by comprehensive stakeholder discussion. This research aims to extract and elaborate our experiences on establishing fisheries sanctuary in the Bangkudulis waters which focus on science communication and in the fisheries sanctuary planning. The acoustic and larva survey conducted to support the consensus and to proof the traditional ecological knowledge of the communities. The results showed that the proposed conservation area of the Bangkudulis waters has significant ecological function to ensure the sustainability of bombay duck population. The distribution and abundance of larva and juveniles were found higher in that area. The approach and challenges to deal with ecological and socio-economic aspects as well as recommendations were discussed in this paper.

Moreover, North Kalimantan Governor Decree No. 26 concerning the management Province established in 2012 is the youngest province of bombay duck (Harpadon nehereus (Hamilton, 1822); in Indonesia (Constitution No. 20 in 2012 concerning Harpadontinae; Synodontidae) fisheries in the North the establishment of North Kalimantan Province), Kalimantan Province’s waters. It was also followed therefore a proper management should be supported by Mayor Decree of Tarakan City No. 24 concerning intensively. the management of bombay duck fisheries in the Tarakan City’s waters. Those regulations were the The regulation recognized that bombay duck outcome of the initiation of Ecosystem Approach to (locally called as “nomei” or “pepija”) is important Fisheries Management (EAFM) in 2012-2014 resource generating economic benefits to the local (Prasetyo et al., 2014).

This resource has been exploited historically by This research is aimed to extract and elaborate trawl fisheries in the certain period (two separate our experiences on establishing fisheries sanctuary periods in a month about 7-10 days per period).
